Activity API

Hi,

I'm trying to access activity data associated with a given UserAccessToken. The request goes through but I keep receiving an empty array, no matter what.

The endpoints in question are:

GET https://apis.garmin.com/wellness-api/rest/activityDetails

GET https://apis.garmin.com/wellness-api/rest/manuallyUpdatedActivities

GET https://apis.garmin.com/wellness-api/rest/activities

Thanks in advance
